Insights
Total occlusion of the left main coronary artery is rare. This case report details a patient with stable angina, demonstrating this unusual finding alongside other coronary artery disease.
Area of Science:
- Cardiology
- Interventional Cardiology
- Clinical Case Reports
Background:
- Left main coronary artery (LMCA) total chronic occlusion is an uncommon clinical presentation.
- Coronary artery disease (CAD) diagnosis and management are critical for cardiovascular health.
- Stable angina pectoris necessitates thorough etiological investigation.
Observation:
- A case report of a patient presenting with stable angina.
- Diagnostic findings revealed total chronic occlusion of the left main coronary artery.
- Associated findings included atherosclerotic lesions in the right coronary artery.
Findings:
- The patient exhibited stable angina symptoms.
- Confirmed total chronic occlusion of the left main coronary artery.
- Right coronary artery demonstrated atherosclerotic lesions with preserved normal ventricular function.
Implications:
- Highlights the importance of considering LMCA occlusion in patients with angina, even if rare.
- Underscores the need for comprehensive coronary angiography in evaluating complex CAD.
- Provides insights into the clinical course and management considerations for such unusual coronary anatomy.
Abstract:
Total chronic occlusion of the left main coronary artery is an unusual finding. After a review of the literature, the authors present a case report of a patient with stable angina and total occlusion of the left main coronary artery, right coronary with atherosclerotic lesions and normal ventricular function.
